AD608

低功耗混頻器/限幅器/RSSI 3 V接收機(jī)IF子系統(tǒng); ? 混頻器\n1 dB壓縮點(diǎn)：?15 dBm\nIP3：?5 dBm\n轉(zhuǎn)換增益：24 dB\n輸入帶寬：>500 MHz;

AD608提供一個(gè)低功耗、低失真、低噪聲混頻器和一個(gè)采用逐次檢測(cè)技術(shù)的完整單芯片對(duì)數(shù)/限幅放大器。此外，AD608提供80 dB動(dòng)態(tài)范圍的高速接收信號(hào)強(qiáng)度指示(RSSI)輸出以及硬限幅輸出。RSSI輸出來(lái)自一個(gè)二極點(diǎn)后解調(diào)低通濾波器，提供0.2 V至1.8 V的可加載輸出電壓。AD608采用2.7 V至5.5 V單電源供電，3 V工作電壓下的典型功耗為21 mW。\n\nRF和本振(LO)帶寬均超過(guò)500MHz。在典型的IF應(yīng)用中，AD608可以接受240MHz表面聲波(SAW)濾波器的輸出，以24 dB的轉(zhuǎn)換增益(ZIF = 165 Ω)將其下變頻到標(biāo)稱10.7 MHz IF頻率。AD608的對(duì)數(shù)/限幅放大器部分可以處理低頻(LF)至30 MHz的任何IF信號(hào)。\n\n混頻器為雙平衡吉爾伯特混頻器，在?95 dBm至?15 dBm的RF輸入范圍內(nèi)線性工作，三階交調(diào)截點(diǎn)標(biāo)稱值為?5 dBm。片上LO前置放大器只需要?16 dBm的LO驅(qū)動(dòng)?；祛l器的電流輸出驅(qū)動(dòng)一個(gè)反向端接的業(yè)界標(biāo)準(zhǔn)10.7 MHz、330 Ω混頻器。\n\n對(duì)數(shù)調(diào)整的標(biāo)稱動(dòng)態(tài)范圍為：當(dāng)IF放大器的正弦輸入為?75 dBm時(shí)，輸出為+0.2 V；當(dāng)輸入為+5dBm時(shí)，輸出為+1.8 V。超出此范圍時(shí)，對(duì)數(shù)一致性典型值為±1 dB。對(duì)數(shù)斜率與電源電壓成比例。反饋環(huán)路自動(dòng)將第一級(jí)的輸入失調(diào)電壓抵消至微伏以下水平。\n\nAD608限幅器提供400mV p-p下的硬限幅信號(hào)輸出。限幅放大器相對(duì)于該輸出的電壓增益超過(guò)100 dB。轉(zhuǎn)換時(shí)間為11 ns；對(duì)于?75 dBm至+5 dBm范圍內(nèi)的信號(hào)，10.7 MHz時(shí)相位穩(wěn)定在±3°以內(nèi)。\n\nAD608由CMOS邏輯電平電壓輸入使能，響應(yīng)時(shí)間為200 ns。禁用時(shí)，待機(jī)功耗在400 ns內(nèi)降至300 μW。\n\n采用2.7 V至5.5 V電源時(shí)，額定溫度范圍為?25°C至+85°C的工業(yè)溫度范圍；采用3.0 V至5.5 V電源時(shí)，額定溫度范圍為?40°C至+85°C該器件采用16引腳塑封SOIC封裝。\n\n
